IMPROVEMENT IN WINDM'ILLS.

Specification forming part of Letters Patent No. E79,? 15., dated June 27, 1876; application filed May 6, 1876.

MILLARD F. INGELS, of Atchison, in the county of Atchison and State of Kansas, have invented a new and valuable Improvement in lindmills; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure]. of the drawings is a representation of a rear view of our windmill, and Fig. 2 is a side view of the same. Figs. 3, 4, 5, 6, and 7 are details of our windmill.

This invention has relation to that class of windmills which will edge more or less to the wind as the force thereof increases or diminishes, thus automatically regulating themselves, and which are, therefore, not liable to destruction by very high winds.

The nature of our invention consists in a shouldered thimble, which is rigidly fixed to the upper end of the tower of the'mili, in combination with rings or hands, whiclrare connected to a shank having rigidly secured to it a rudder-vane, said rings allowing the vane to articulate freely about the said thimble on which they are placed, as will be hereinafter explained.

Our invention also consists in an angular bracket, which affords bearings for the wind wheel shaft, and which is constructed with rings or hands applied on the thimble at the upper end of the mill-post, and which are free to turn about the same independently of the vibration of the vane, as will be hereinafter explained.

The invention further consists in combining with the above-mentioned bracket a curved arm, which springs from the upper band of this bracket, and is connected to the shortest arm of an angular lever, which has its fulcrum on the rudder-vane, and which has applied to it an adjustable weight, which operates to keep the wind-wheel face to the wind, as will be hereinafter explained.

In the annexed drawings, A designates the tower of our windmill, which may be constructed in any suitable manner, and which has secured to its upper end a thimble, B, having a shoulder, a, formed on it. On this thimble are four rings or bands. Two of these bands, 1) D are formed on a broad fiat shank, O, to which is rigidly secured a rudder-vane, D. The lower band I) is supported upon the shoulder a, and the upper band b has formed on it an elevation, D to which a pulley is applied. Over this pulley is passed a rope or chain, c, which passes down through the thimble B, and may be attached to a cleat on the tower A, in a convenient place for use. This rope or chain c is connected to the short angular arm of the lever E, which has its fulcrum at e on the neck of the rudder-vane D, and which carries on its longest arm an adjustable weight, f. By the gravitation of this weight f the wind-wheel is held face to the wind, in which position the rudder-vane is at right angles to the plane of the wheel. As the force of the wind increases, the wheel will be caused to edge more or less to the wind, and when the force of the wind is very great the rudder-vane will be brought around parallel with the plane of the wheel,

and the latter will cease rotating.

It will thus be seen that the angle of the wheel with respect to the rudder-vane will be increased or diminished according to the force of the winda feature which is not herein broadly claimed.

F designates a bracket, suitably braced, which is constructed with journal-boxes on its horizontal. portion, that affords bearings for the shaft g of the wind-wheel, and it is also constructed with a curved arm, n, which is connected by arod, n, to the short arm of the loaded lever E.

The journal-boxes above referred to are set off on one side of the vertical axis of the thimble B, as shown in Fi .1. This bracket F has bands h h formed on it, which are connected by a bar, h at the upper end of which bar is pivoted an angular lever, 6. One arm of this lever is connected by a pitman-rod, G, to a pump-rod, G. The other end of this lever i is connected to a crank, 10, on the end of the' wind-wheel shaft 9 by a rod, 70. The pumprod thus receives a vertical reciprocating motion from the short arm of the lever *5.

Our improved wind-wheel is constructed as follows: I I designate rings, which are edge- 'are angularly notched and flanged, as designated by the letters l in-Figs. G and 7. The angular flanges have bolted to them the blades J of the wind-wheel. The blades are tapered and feathered, as shown in Fig. 1, and they are arranged in lines, which are tangent, or nearly so, to the opening through the center of the wheel, the angle being about fifteen degrees to the diametrical plane of the inner ring I. The letters K designate the spokes of the Wind-Wheel, which are rigidly secured to a flanged spider, m, which spider is keyed to a shaft on the wind-wheel g, so that they are dished like the spokes of a wagon-wheel, for the purpose of bracing the wind-wheel.

The face of the wind-wheel is flat, or nearly so, which flatness is obtained by securing the spokes K to the edge of the inner ring I, by means of clips or their equivalent. The outer ends of the said spokes abut against the inner side of the outer ring I, and are secured thereto by nails driven through this ring and into the ends of the spokes.

What we claim as new, and desire to secure by Letters Patent, is

1. In a windmill, the shouldered thimble B, rigidly secured to the tower A, in combination with rings orbands b 1) formed 011 a shank, O, to which is secured the rudder-"ane D, and an elevation, b carrying a pulley, over which a rope, 0, passes, which is connected to the short arm of a loaded lever on the rudder-vane D, substantially as described.

2. The angular bracket F, formed of bands h h which play about the thimble B; also, with an arm, a, which is connected by means of a rod, n, to the short arm of the loaded lever E, in combination with a Wind-wheel, the shaft of which is journaled on said bracket, and connected by a crank and-lever to the actuating pump, as set forth.
